P0104 2017 Ford F150 Code - Mass Or Volume Air Flow Sensor 'A' Circuit Intermittent

Quick Answer

The Mass Airflow (MAF) Sensor uses a hot wire sensing element to measure the amount of air entering the engine. Common causes include Dirty Air Filter, Faulty Mass Airflow (MAF) 'A' Sensor, Mass Airflow 'A' Sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0104 2017 Ford F150 Description

The Mass Airflow (MAF) Sensor uses a hot wire sensing element to measure the amount of air entering the engine. The air passing over the hot wire causes it to cool. This hot wire is maintained at 200°C (392°F) above the ambient temperature as measured by a constant cold wire. The current required to maintain the temperature of the hot wire is proportional to the mass airflow. The MAF Sensor then outputs a signal to the Powertrain Control Module (PCM) proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air to fuel ratio. The MAF sensor is located near the air cleaner assembly. Most MAF sensors have an integrated Intake Air Temperature (IAT) sensor. This Diagnostic Trouble Code (DTC) will be set when a concern exists in the MAF circuit, or the air tube containing the MAF Sensor, causing an incorrect sensor output reading.

Frequently Asked Questions about P0104 2017 Ford F150 Code

1. What does the OBDII code P0104 indicate on a 2017 Ford F150?

The P0104 code indicates that there is an intermittent signal from the Mass Air Flow (MAF) sensor 'A' to the Engine Control Module (ECM), suggesting fluctuations or irregularities in the sensor's readings or its circuit.

2. What are the common symptoms of code P0104 in a 2017 Ford F150?

Symptoms may include a rough idle, decreased fuel efficiency, engine stalling, hesitation during acceleration, and the Check Engine Light turning on.

3. What can cause the P0104 code to appear on a 2017 Ford F150?

Possible causes include a faulty or dirty MAF sensor, loose or corroded connections in the MAF sensor circuit, a vacuum leak near the MAF sensor, or a problem with the ECM itself.

4. How can I diagnose the P0104 code in my 2017 Ford F150?

Start by inspecting the MAF sensor and its connections for any signs of damage or corrosion. Check for any loose or disconnected vacuum hoses around the sensor. Use an OBDII scanner to check for additional diagnostic trouble codes and to monitor the MAF sensor's output while the engine is running.

5. What are the repair steps for addressing code P0104 on a 2017 Ford F150?

First, clean the MAF sensor using a specialized cleaner. If the issue persists, check and repair any faulty wiring or connectors in the MAF sensor circuit. If these steps do not resolve the problem, consider replacing the MAF sensor.

6. Can I drive my 2017 Ford F150 with the P0104 code active?

While you can technically still drive, it's not recommended as the engine might perform poorly, stall, or use more fuel than usual. It's best to address the issue promptly to avoid potential further damage to the engine.

7. What tools are needed to fix the P0104 code on a 2017 Ford F150?

You'll need a digital multimeter to check the MAF sensor and circuit continuity, a specialized MAF sensor cleaner, and basic hand tools for removing and installing the sensor or related components.

8. How much does it typically cost to resolve code P0104 in a 2017 Ford F150?

The cost can vary, but generally, cleaning the MAF sensor might cost around $50 to $100 if done professionally. If a MAF sensor replacement is needed, the parts and labor can range from $200 to $400 depending on the sensor's cost and the labor rates.

9. Is the P0104 code a serious concern for the overall health of a 2017 Ford F150?

Yes, it should be taken seriously as an improperly functioning MAF sensor can lead to decreased engine performance, increased emissions, and potentially more serious engine issues if not addressed in a timely manner.
